  • Wide operational temperature range from -40° to 140° F maintains integrity in varying thermal conditions without degradation.
  • Compliance with UL 94 V-2, RoHS 3, and REACH standards ensures safety, environmental responsibility, and suitability for regulated industries.
  • Fully threaded M4 x 12mm design provides uniform clamping force and versatility across diverse assembly applications.
  • Lightweight and chemical-resistant properties of nylon reduce overall weight and enhance durability against many industrial substances.

Professional Applications & Engineering Value

This M4 metric socket head cap screw is engineered to address common industrial challenges such as corrosion, electrical hazards, and stringent regulatory demands. Crafted from Nylon Plastic, it offers inherent resistance to moisture, chemicals, and electrical conductivity, making it perfect for electrical enclosures, automotive components, and consumer electronics where non-conductive and lightweight fasteners are critical. The Class 6g thread fit and coarse pitch ensure quick, reliable assembly with reduced cross-threading risks, while the hex drive and socket head allow for high torque application in confined spaces. Its ability to perform across a broad temperature range and meet UL 94 V-2, RoHS, and REACH standards provides engineers with a dependable solution for projects requiring safety, durability, and compliance.

Specification Summary & Compliance

This screw adheres to metric coarse thread standards with precise Class 6g thread fit for consistent dimensional accuracy. It is manufactured in compliance with UL 94 V-2 for flammability safety, RoHS 3 (2015/863/EU) for hazardous substance restriction, and REACH (EC 1907/2006) for chemical management, ensuring full regulatory alignment in industrial applications.
